+1 on 95%+
I'm partial to Carrier Equipment, but you need to have hte Performance series quoted. I also think you should alwasy price, good better and best. I'd alos price out a York Affinity modulating furnace and a Carrier Infinity both with 2 stage AC.
Thanks. Will look into Affinity models

York is the major brand that we sell, so i'm probably biased. The TM9V is a really good furnace and I love the LX series of AC and heat pumps, much more than the York affinity. It is cheaper and I believe it's a better system. You can match the 14.5 Seer outdoor unit with variable speed motor and txv to achieve almost 16 Seer. I think with the 3 ton it will match to 16 Seer and the others are 15.6+. We have installed many like this and have had no problems... knock on wood

2300 sq ft 1992 home shouldn't need a big furnace. Above average number of windows, maybe a 80,000 95plus% furnace.
On the coldest days, did your current 114,000 80% have to run 24/7 to keep your house warm? or did it cycle on and off.

Current furnace cycles on and off with what seems to be a normal frequency. Never had an issue with lack of heat or inability to maintain temp.

Your current furnace has a rated output of 91,200 BTUs. So you don't need a 100,000 BTU 97% furnace. You probably do need a proper load calc done to find out what size you really need.

What is "normal"?
Were your Jan. gas bills close to $400 in a colder winter (last year doesn't count)? IF not, 114k is oversized.
